Figure 6
Sequence logos of sequences identified through a database search with part of the LfCE15C sequence (see Section 2[link]). The top shows the logo of all sequences, the middle the logo of the subset with glutamate at position 3 and the bottom the logo of the subset with glycine at position 3. Practically all sequences found have the isoleucine characteristic of CE15-B (see Fig. 1[link]a) at the position occupied by the acid in CE15-A (blue arrow), and thus can be assigned to CE15-B despite the unusual sequence features. The position of the tryptophan or tyrosine residue found to correlate with the presence of either a glutamate or glycine residue, respectively, is shown.
